To all whom it may, concern/.-

Be it known that l, 5 hi Swim, citizen of the United States, residing Sterling, in.

the county of W'hiteside and btate of lllinois, have invented certain new and improvements in Hay-Loaders; and i do declar the following to he a full, clear, and exact description of the invention, such will enalole others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form apart of this specification.

My invention has reference to hay-lcaders, and comprises certain novel levices for moving the hay from the other novel mechanism for conveying or elevating the hay from said first-named devices to the wagon to be loaded thereon. lalso provide a novel means for gradually raising the upper end of theelevator mechanismas the loading operation progresses. These and other advantages of my invention will more full appear from the following specification, rel erence being had to the drawings accompanying the same, i whicl *igure 1 is a plan view of my device. Fig. 2 is a side elevation thereof. Fig. 3 is a detail showing one end the cylinder 9 and cam 21 adjacent thereto. Fig. l is a detail showing one of the teeth e8. Fig. 5 is a detail showing a portion of one of the rake-bars 18. Fig. 6 is a vertical longitudinal section in the line :0 w of Fig. i. Fig. 7 is an end elevation of the rake-cylinder 9 and supporting mechanism therefor. Fig. 8 is a detail showing a section of the inner face of one of the sides 26 and method of vibrating the lower ends of the elevator hars. is a detail showing part of the elevator-bars in crosssection and manner of supporting same.

Similar numbers refer to similar parts throughout the several. figures.

l l are the carrying-wheels on short shafts 2, supported at their inner ends on the frame 8 and at their outer ends on supports 4,. fixed to the frame 3. .ln 2, 3, and is shown a l1and-lever 5, iulcrumed its forward end on the shaft and supporting one end of a rotary shaft 6, on the ends of which are fixed gear-pinions 7, actuated by ear-wheels 8 on the shaft 2 Fixed on the shaft 6 is a rake cylinder 9, provided at each end with a head 10, each of such heads having a plurality of equidistant radial slots 11, preferably four in number.

l ixed on the frame 3 at each end of the cylinder 9 is support 12, to which is fastened the upper end oi a brace 33, the lower end of such brace being curved rearwardly and fixed to the frame in the curved ortion of the brace 1s a series of holes 14, a olt passing through one of said holes and through s perforation 16 in the lever 5. This furnishes a support for the rear end of such lever.

each end of the cylinder 9, on the inner thereof, are two racks 17, the bars of loosely embrace the shaft 6. Extendongitudinally of the cylinder are four tooth hars the ends of which are secured the ends of the racks 17. In the ends of 18 are fixed small stud-shafts 19, -ch severaiy pro lect through the slots 11 and have rollers 20 on their outer ends. Supported on its inner faces track 22, (shown in dotted lines) which engages each of the rollers 20 in succession during aportion of the rotation of the cylinder 9. Each end of the cylinder is the lever 5 is a cam 21, having on orovided with one of the cams 21', (only one heing shown,) which cams act coincidently upon the rollers 20 on the ends of each toothbar Each of the bars 18 is provided with a plurality of teeth 23, each of such teeth being rendered flexible near its point of attachment to the bar by means of a coil 24 in such tooth. The teeth are adapted to be projected outwardly from the cylinder through a series of openings 25, provided in such cylinder in line with each row or the teeth.

Themovement of the machine causes the cylinder 9 to rotate in a direction contrary to that of the wheels 1, and when not otherwise controlled the tendency of the tooth-bars 18, by reason of the weight thereof, is to maintain a position at the lower side of the cylinder with the teeth 23 protruding therefrom. As the cylinder continues to rotate, the rollers 20, on the ends oi one of the bars 18, are engaged by the cams 21, the form of such c ns being such that said bar is gradually drl vn toward the center of the cylinder, the tee within. the cylinder until when they arrive at the upper side thereof they have entirely disappeared. The cars l8 being fastened together in pairs, as the teeth recede on one side of the cylinder they are gradually projected on the opposite side, so that they are in posit on to engage the hay on the ground err-Li. drew upwardly 3e seen that the two sethus controlled and aotw ztion oi the came 21, and f the th tooth-h er of the egernent with such earns hers and the teeth. thereaction of t eth just ed open shown.

At int of junction of the teeth and. loop the teeth are swine-ingiy attached to the sid es of the here 42 the :p 4.9 being normally in cross iiecc 37 z 4 til),

"ill oi the I l l l l erect? contact with the upper face of the bar end at such an angle to the teeth as to limit their rearward movement to practically a right angle to the bar extending downwardly therefrom. They are, however, permitted to swing forwardly and upwardly into line with the her, as shown in Fig. 4.

Parallel with tlie'cross-pieces 37 and alter neting therewith is a similar pair of crossoieces 50, also provided at their ends with rollers 38, running on the tracks 39. Pitinen '51 are pivotelly attached at their forward ends to the rear ber and at their rear ends to cranks 52 in the shaft 43,1tl18 cranks 52 being disposed. upon the shaft 43 diametrically ooposite to the cranks 42. Supoorted from 1e cross-bars 50 is c series of elevator-hers 58, alternating provided with a plurality oi swinging teeth By the rotation of the shaft 43 during the operation of the machine the bars 47 end 53 sre given an alternating reciprocating movement longitudinally oi the machine, causing the teeth 48 to engage the hey at the lower end of the elevator and by successive stages convey it to the upper end thereof. in

the upward. movement of the elevator-hers the teeth ere embedded deeply in the hey,

but in the rearward movement the teethswing upwardly and slide over the hay, egcin engaging the same at the lower end of the stroke. As one set of bars alternates with.

othcrthe movement of the hey is prectically contiinimis. The swinging action of the teeth permits the movement of all of the elevator-bars in the same plane, but, if desired, a vertical movement may be given to the lower ends of such hers by the means shown in 8. Pivoted on the inner face of the side 26 is a. air of wed ge-sheped cams 5 one ofwhich is engaged by the roller 38 on the lower crossrpiece 37 and the other by the roller 38'on the cross-piece 50. The free ends of the cams extend forwardly and normell I rest upon the track 39. .ln the rearwer movement of the cross-pieces the rollers pass along the upper edges oi the cams, dropping therefrom to the track, and in the return movement pass under the cams, such cems being raised thereby and dropping with the bars 47 and similarly again into contact with the track after the passage of the rollers. To prevent the interference of the cross-pieces of one set of bars with the bars of the other set in the operation just described, it is necessary to suspend the elevator-hers independently at a little (listance below their rospcoti ve crosspiec0s, and this is accomplished by the use of blocks 55 or similar means. Gems 54 are provided for the rollers 38 at each end of the lower crosspiecos, only one pair thereof being shown in the drawings. By this construction the teeth 48 at the rear ends of the bars are not only permitted to swing upwardly and pass over the hey, butthey are elevated slightly wheel 31,

above the 1e, so to ttacilita tion of the teeth into the hay a to the line of movement thereof. this i'i'iechanism is optional, howe' not esse tial to the successful ope the machine,

At the rear ei'id oi. the elevator is 1 comprising; back pi no" braces and .58, secret 7 it and side piece respectively, a board 59 on a line ith the upper in cylinder 9. By this means the hay i vented from being carried over the top I: I 0i mi? cylinder and to the rear thereof, but is held above the cylinder until it is engaged. by the elevator-teeth in their rearward move ment the elevator-bars extend suliicient distance beyond the lower end oi'the ole" vator'fioor l enable the lower teeth thereon to seize the any supported by t Journaled beneath the side piece 26 near the wheelZ-Bl' is a rotary shaft "'0 on. which fixed a small gee '-wheel (51, inesiii There is also securer a ratch wheel 62, actuat. arm 63, pivot-ed on the shaft the'side of the pitman 41 is a vidcd with a pin 65, engaging the upper end of theratchet-arm 63, so as to move such. arm rearwardly at each rearward movement of the pitman, thus causing the rotation of the shaft 60 and imparting the movement thereof through. the wheels 61 and 31 to the drum 32. The rope 35 is shortened by being wound upon the drum and the forward end l on irame 64, proof the elevator raised, as hereinbeiore (ls-- scribed. A 6% on the side 26 prevents the backward rotation of the ratchet-wheel 62, while a coiled spring 67, fined at one end to the side 26' and at the other end to the arm 63, causes such. arm to return to its former position upon the return stroke oi the nitman ll. 68 is a rod adjustably held at its front end in a bracket 69 by means of a setscrew 70. At its rear end the rod 68 is provided with a pin 7 i, engaging the upper end of the ratchet-arm By mevingthe rod 68 rearwardly the forward movement of the arm 63 is correspondingly limited and the movement of the ratchet-wheel 62 decreased- This also lessens the movement of the drum 32 and front end oi the elevator is raised more gradually.

it the iorward end of the elevator per- 6 5 r to be easily adjusted by the operator the wagon. e ferward end of the elevator is raised end thereof'roclrs rearwardly on the I t 28, as shown in broken lines in Fig. 70 reason of the fact that the support i to is pivoted just above the cen 1 1 ,he cylinder 9 in the movement he elevator the lower end thereof, the rd in rear thereof, and the upper face of -.evator maintain practically the same ,tive positions and the passage-way for the hay between the cylinder and the lower oi the elevatontloor is not I varied in wid 1h.

ii desired to raise or lower the cylinder 9, i g the teeth 23 farther away from carer to the ground, this can be done by ,ustment of the levers 5 upon the braces Such chane in the position of the cyl- 'nder does not (.isturb the relative positions the parts appurtenant thereto, all of such invention, and desire 0 of the United scribed.
